Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655766, here are decompositions:

5 + 8655761 = 8655766
17 + 8655749 = 8655766
47 + 8655719 = 8655766
59 + 8655707 = 8655766
89 + 8655677 = 8655766
113 + 8655653 = 8655766
137 + 8655629 = 8655766
239 + 8655527 = 8655766

Showing the first eight; more decompositions exist.
